Interface Not Supported – Windows 7

Windows 7 has been working well, but the other day it just stopped being happy and refused to launch any Explorer windows (like file manager).  It said, “Interface Not Supported” and that was it.  Come on Microsoft, please be a little better about your errors and give some information.  I google’d for a while and found a fix.  Re-register all the DLLs.  I just pasted the following into the command prompt. All fixed up.

    Dont work for me. I run as administrator on cmd.exe (c:Windowssystem32>) and typed all that code and entered “line by line” all commands but they doesn’t show any msg when inserted.

    Then I tryed to see whit the right click mouse on personalization menu, or monitor resulation and the message is the same: “Interface Not Supported” …

  18. Jade Jade

  20. Psher Psher

    dont work for me 🙁
    please help me to resolve this problem :/

  21. This didn’t work for me, either. I had the message “Explorer.EXE Interface not supported” with the EXE in capital letters, which is an indicator of a virus in the system. I got rid of it after rebooting in safe mode (push F8 on boot-up) and doing a complete system scan by Avira. It found a virus and deleted it. After that all was good again. HTH.

  22. yay! web site doesn’t work in ie7…already upgraded current computer to ie8…hadn’t yet found ietester…stupidly tried to install ie7 – i know, i have no idea what i was thinking. ran cmd.exe as administrator and pasted it in – explorer started working without even a reboot! excellent!

  23. Prosa Prosa

    Great, It works! However I’ve removed the ‘rem’ before

  24. peter peter

    Yes its working, thanks

  25. Jaeden Jaeden

  30. Kris Kris

  31. Anthony Anthony

  32. Qualanqui Qualanqui

    Tried this and it didn’t work, had to run it as a startup batch script because cmd.exe doesn’t work but it still comes up with “Interface Not Supported” when I try to open anything so I have been forced to create a new user which also isn’t doing very well god I hate windows why must EVERYTHING be so dam difficult?

  33. Rocl Rocl

    Thank you ! it worked for me !

  34. Keven Keven

    Didn’t work.
    Here is what worked for me:

    I found a thread about doing such weird stuff in a batt file. It was about Win98…
    I googled a bit more and found that magic command:
    FOR /R C: %G IN (*.dll) DO “%systemroot%system32regsvr32.exe” /s “%G”

    It took about 2 min and showed up a LOT of errors like ” Runetime error! ”
    Just click ok on allll of them.

    When the command is done… ENJOY 😀
